The succession of Quaternary deposits and morphological forms at Potter Peninsula. Maxwell Bay, King George Island (South Shetland Islands, West Antarctica) includes: (1) raised residual gravel and remains of marine abrasion surfaces, 97-118 m a.s.l. (Pleistocene); (2) marine (fjord-bottom) silty and sandy beds with bivalve shells (radiocarbon-dated at early Holocene); (3) highest raised marine terraces, 40-50 m a.s.l. (early Holocene); (4) older moraines - the Punta Batiza glaceir advance stage (mid-Holocene); (5) high raised marine terraces, 22-25 m a.s.l. (late Holocene); (6) low raised marine terraces, 7.5-12 m a.s.l., and raised marine beaches, 2-16 m a.s.l. (late Holocene); (7) younger moraines, outwash cones, kame terraces etc. - the Potter Cove glacier advance and retreat stages (latest Holocene). The Holocene isostatic land uplift at Potter Peninsula, is calculated at about 50 m.
